Description
Technical field
The invention belongs to technical field of wind power generation, swing more particularly to a kind of flexibility suitable for vertical-axis wind turbine
Formula pod.
Background technique
Wind energy is as a kind of clean energy resource, and the specific gravity for accounting for traditional energy is increasing, and vertical-axis wind turbine is one
The kind more extensive wind energy generating plant of use scope.
Currently, since traditional vertical-axis wind turbine has the resistance area for accounting for cut-off wind half of the area, cause traditional vertical
The power coefficient of axis wind turbine is not high, in order to improve this problem that traditional vertical-axis wind turbine faces, technical staff
A pod would generally be increased outside wind turbine, the wind guiding for flowing to resistance area originally is generated by power by pod
Side, to play the role of certain wind gathering, to increase the efficiency of wind turbine.
Existing pod is roughly divided into two types, the first is the pod that can be swung with box haul, another
Kind is fixed cage modle pod, and existing two kinds of pod has certain shortcoming.
For the first pod, certain response time is needed, and needs additional configuration pod tuning
Mechanism, and it is difficult to realize enlargement.
For second of pod, total quality is heavier, and the leeward idle side of the wind energy conversion system at pod center
Still resistance can be generated, therefore diversion effect is not very ideal.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of flexible swing type suitable for vertical-axis wind turbine and leads
Stream cover, have the characteristics that light weight, can adapt to full blast to, without additionally configure pod adjusted device.
To achieve the goals above, the present invention adopts the following technical scheme: a kind of flexibility suitable for vertical-axis wind turbine
Swing type pod, including upper bracket, lower bracket, flexible blade and blade fixed frame；The blade fixed frame is vertically installed at
Between upper bracket and lower bracket, the flexible blade is mounted on blade fixed frame, and flexible blade quantity is several, several flexible leaflets
Piece is uniformly arranged in a circumferential direction；It is isosceles trapezoid that the flexible blade, which is launched into the shape after plane, when flexible blade is pacified
After being attached to blade fixed frame, four angle points in the flexible blade of isosceles trapezoid are located in the same perpendicular；In isosceles ladder
The long bottom edge of the flexible blade of shape is free end, and the short bottom edge in the flexible blade of isosceles trapezoid is fixing end.
The quantity of the flexible blade is 4~16.
Installation angular region in perpendicular where four angle points of the flexible blade of isosceles trapezoid is ± 30 °.
In the short bottom edge of the flexible blade of isosceles trapezoid, long bottom edge, length bottom edge common vertical line height proportionate relationship
Are as follows: short bottom edge: long bottom edge: length bottom edge common vertical line height=1:(1.01~1.1): (0.2~0.45).
Beneficial effects of the present invention:
Flexible swing type pod suitable for vertical-axis wind turbine of the invention has light weight, can adapt to full blast
To, without additional configuration pod adjusted device the characteristics of.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of flexible swing type pod suitable for vertical-axis wind turbine of the invention；
Fig. 2 is the working state figure of the flexible swing type pod suitable for vertical-axis wind turbine of the invention；
In figure, 1-upper bracket, 2-lower brackets, 3-flexible blades, 4-blade fixed frames, 5-wind turbines.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of flexible swing type pod suitable for vertical-axis wind turbine, including upper bracket 1, lower bracket
2, flexible blade 3 and blade fixed frame 4；The blade fixed frame 4 is vertically installed between upper bracket 1 and lower bracket 2, described soft
Property blade 3 is mounted on blade fixed frame 4, and 3 quantity of flexible blade is several, and several flexible blades 3 are laid in a circumferential direction
It sets；It is isosceles trapezoid that the flexible blade 3, which is launched into the shape after plane, after flexible blade 3 is installed to blade fixed frame 4,
Four angle points in the flexible blade 3 of isosceles trapezoid are located in the same perpendicular；In the length of the flexible blade 3 of isosceles trapezoid
Bottom edge is free end, and the short bottom edge in the flexible blade 3 of isosceles trapezoid is fixing end.
The quantity of the flexible blade 3 is 9.
Installation angular region in perpendicular where four angle points of the flexible blade 3 of isosceles trapezoid is 30 °.
In the short bottom edge of the flexible blade 3 of isosceles trapezoid, long bottom edge, length bottom edge common vertical line height proportionate relationship
Are as follows: short bottom edge: long bottom edge: length bottom edge common vertical line height=1:1.05:0.25.
After traditional vertical-axis wind turbine uses flexible swing type pod of the invention, and flexible blade 3 and wind
The rotation direction of turbine blade keeps inverse state to be installed, as shown in Fig. 2, can make first after wind acts on pod
The free end of the flexible blade 3 of windward side is flapped toward center of circle side, at this time can be oriented to a part by the wind of wind turbine resistance area
Power face, the windward side air-admitting surface of flexible blade 3 is greater than leeward side outlet air open area at this time, and then can produce jet pipe effect
It answers, wind speed is made to be further strengthened, so that the efficiency of wind turbine 5 is also further increased.
Meanwhile it can be flapped toward circumference in the free end of the flexible blade of leeward side 3, flexible blade 3 and wind turbine leaf at this time
Biggish angle and lesser air outlet are formed between piece, and the reaction force of air-flow and flexible blade 3 can be applied to again
On wind turbine 5, to further enhance the positive torque of wind turbine 5, and then the efficiency of wind turbine 5 is improved.
The scope of patent protection that scheme in embodiment is not intended to limit the invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the patents of this case.
